Only saw the pictures of the steelies now and DAMN they are awesome!!!

Hi Tom, this is very interesting. Why did the discs make it worse? I would have thought otherwise.

This is my proof that the Golf disks in a beetle is inferior to the standard Drums. I am sure that if i fitted a booster the brakes would have been OK.

End of Story.

The bus is now down to floor level.

This is the type of ground clearance we hoping to achive.

No building this comming weekend.

Son and I got to work this weekend, Setting up for Hostex. Some times you need to find a way to pay for your hobby.

My Son has organised a trailer for Saturday after noon.

This means Big Toe is comming to my palour on Sunday to be slaughtered.

Its taking the place of scoob bug at my shop.

So more pics to come That is serious ground clearance and I know loads of people are going to be very

Tom Jr, you making the old man do all the work and the updates on the site......now that's just not cricket!

I think you should do this but with the Big Toe body on!

hmmmm! Sounds like a plan

on saturaday BIG TOE will be brought to the slaughter house and will be no more BUT from the ashes of BIG TOE will be born BABY HUEY!!!

RIP BIGTOE RIP

Sorry Tom but I got to disagree with you on this point!
With the size of those wheels Golf Mk1 disks would have a problem retarding the huge rotational mass BUT it you had gone with a larger diameter disk like the VR6 disks you would not have had any issues!!! Plus you are talking about a single pot calliper compared to a twin pot calliper! Big difference...Its simple maths!
You cant generalise and say "This is my proof that the Golf disks in a beetle is inferior to the standard Drums." because this is misleading! In this particular scenario you may be correct due to the incorrect application, but golf Mk1 disks in a 15" mag on a beetle is 200% better than drums will ever be. No fade, no constant drum setting, no pulling to one side on hard braking, no oval drum wear....
Look at the application you want to use the disks in and then choose the correct equipment for the job at hand....

You get a new Gas mix? cause this one is working well!

Other than a good gas mixture how can you disagree.

Braking time of a SP Beetle and the Last Citi is the same. How can it be 200% better if you take the braking system from the Citi and lose the booster. Remember that a booster will multiply the maximum pressure you can apply with you foot.

The 200% better is on maintenance not on emergency braking. The better braking in the 15" mag comes from the lighter spinning mass not the Disks.

Add a booster and your story about will hold water. If not I stick to my story. The larger wheels just multiplied the problem.

Discussion Closed from my side. Come to my workshop and I will explain it to you.

I dont have to come anywhere.... My proof lies in the DarkSide's stopping power....

Come for a drive in the DarkSide and the benefits will be self explanatory.

You cant compare the drums on a Beetle to the disk on a golf... The '67 beetle (840kg)is lighter than the golf (just under a ton). Of course they will have similar braking times.

A Brake booster is an enhanced master cylinder setup used to reduce the amount of pedal pressure needed for braking. It employs a booster set up to act with the master cylinder to give higher hydraulic pressure to the brakes and/or lower force applied on the brake pedal. The brake booster usually uses vacuum from the engine intake to boost the force applied by the pedal on to the master cylinder, or may employ an extra vacuum pump to enable it. Without the engine running the brake pedal feels very hard and ineffective on the braking capability.

Here is a challenge for you then.... Bring ANY beetle with drums and I will out brake them with the DarkSide over 10 or 20 stops from 100km/h. And then you'll have your proof!!!!

Maybe you should try some of my gas mixture it might remove that mental block your having.....

Sorry Vader, I said the topic is closed but please base you comments on facts and not opinion.

I just checked the weight of one of my Citi Golfs, 847KG.

From your Copy and Paste ( http://en.wikipedia.org/wiki/Brake_booster ) there are two points I would like to point out to you.

1) A Brake booster is an enhanced master cylinder

and

2)Without the engine running the brake pedal feels very hard and ineffective on the braking capability.

Do you understand that with out the engine running, you have the same effect as not fitting a booster and as you correctly stated :"the brake pedal feels very hard and ineffective on the braking capability"

If there is some part of this that you dont understand, please come visit me.

In every day driving how many people make 10 > 20 emergency stops. In real life when a kid runs out in front of you car, you only get one chance.

Come ride with me and I will show you a new world of braking.

OK Last post, Promise...
